The communication module 190 may support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device 101 and the external electronic device (e.g., the electronic device 102, the electronic device 104, or the server 108) and performing communication via the established communication channel. The communication module 190 may include one or more communication processors that are operable independently from the processor 120 (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network 198 (e.g., a short-range communication network, such as Bluetooth^TM, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network 199 (e.g., a long-range communication network, such as a cellular network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module 196.

The antenna module 197 may transmit or receive a signal or power to or from the outside (e.g., the external electronic device) of the electronic device 101. According to an embodiment, the antenna module 197 may include an antenna including a radiating element include a conductive material or a conductive pattern formed in or on a substrate (e.g., PCB). According to an embodiment, the antenna module 197 may include a plurality of antennas. In such a case, at least one antenna appropriate for a communication scheme used in the communication network, such as the first network 198 or the second network 199, may be selected, for example, by the communication module 190 (e.g., the wireless communication module 192) from the plurality of antennas. The signal or the power may then be transmitted or received between the communication module 190 and the external electronic device via the selected at least one antenna. According to an embodiment, another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as part of the antenna module 197.

At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)).

According to an embodiment, commands or data may be transmitted or received between the electronic device 101 and the external electronic device 104 via the server 108 coupled with the second network 199. Each of the

electronic devices

102 and 104 may be a device of a same type as, or a different type, from the electronic device 101. According to an embodiment, all or some of operations to be executed at the electronic device 101 may be executed at one or more of the external

electronic devices

102, 104, or 108. For example, if the electronic device 101 should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device 101, instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service. The one or more external electronic devices receiving the request may perform the at least part of the function or the service requested, or an additional function or an additional service related to the request, and transfer an outcome of the performing to the electronic device 101. The electronic device 101 may provide the outcome, with or without further processing of the outcome, as at least part of a reply to the request. To that end, a cloud computing, distributed computing, or client-server computing technology may be used, for example.

The electronic device according to various embodiments may be one of various types of electronic devices. The electronic devices may include, for example, and without limitation, a portable communication device (e.g., a smartphone), a computer device, a portable multimedia device, a portable medical device, a camera, a wearable device, a home appliance, or the like. According to an embodiment of the disclosure, the electronic devices are not limited to those described above.

An electronic device (e.g., electronic device 101 of FIG. 1) may match an output power of a transmission signal with an output power of a transmission signal demanded by a base station. The electronic device 101 may detect the output power of the transmission signal, and may adjust the strength of the output power of the signal being transmitted by the electronic device 101 in comparison with the transmission output power demanded by the base station. For example, the electronic device 101 may adjust the strength of the output power of the transmission signal by controlling the gain of a processor (e.g., communication processor (CP) or coprocessor 123) or a power amplifier (PA) of a transceiver.

In case the electronic device 101 can process signals of a plurality of frequency bands, but does not simultaneously transmit or receive the plurality of signals, only one circuit configuration is sufficient to detect the outputs of the transmission/reception signals. However, with the development of technology, the electronic device 101 can simultaneously transmit and/or receive the signals of the plurality of frequency bands.

Hereinafter, according to various example embodiments of the disclosure, an example method and configuration will be described, in which the electronic device 101 detects signals of a plurality of frequency bands being simultaneously transmitted and/or received.

According to various example embodiments of the disclosure, an electronic device 101 can process signals through time division for each frequency band.

FIG. 2 is a diagram illustrating example signals being detected by an electronic device for each frequency band in terms of time according to various embodiments of the disclosure.

As illustrated in FIG. 2, an electronic device (e.g., electronic device 101 of FIG. 1) may detect a transmission signal of a first frequency band at a first interval (t₁ to t₂) (210), and may detect a reception signal of a first frequency band at a second interval (t₂ to t₃) (220). The electronic device 101 may detect a transmission signal of a second frequency band at a third interval (t₃ to t₄) (230), and may detect a reception signal of a second frequency band at a fourth interval (t₄ to t₅) (240).

In an embodiment, time required to detect respective signals may be constant or may differ. The order of detecting the signals may not be limited.

For example, if the electronic device 101 supports an ENDC technology, the first and second frequency bands may be respective frequency bands being used in a long term evolution (LTE) or new radio (NR) communication system. For example, if the electronic device 101 is a device supporting a CA technology, the first and second frequency bands may be different frequency bands being simultaneously used in one communication system.

FIG. 3 is a diagram illustrating an example partial configuration of an electronic device according to various embodiments of the disclosure.

With reference to FIG. 3, an electronic device (e.g., electronic device 101 of FIG. 1) may include a communication processor (hereinafter, "CP") (e.g., including processing circuitry) 360, a transceiver 370, and a plurality of front end modules (hereinafter, "FEMs") 310, 320, 330, 340, and 350.

The CP 360 may include various processing circuitry and transmit and/or receive data through the transceiver 370, and as needed, may control the FEMs. The transceiver 370 may transmit and/or receive signals to and/or from at least one of the

FEMs

310, 320, 330, 340, and 350.

According to an embodiment, the electronic device 101 may include at least one of the first to

fifth FEMs

310, 320, 330, 340, and 350 processing the signals being transmitted and/or received. For example, the first to

fifth FEMs

310, 320, 330, 340, and 350 may be formed by frequency bands.

According to an embodiment, each of the first to

fifth FEMs

310, 320, 330, 340, and 350 may include at least one of a coupler 312 detecting the signals being transmitted and/or received, a power amplifier (hereinafter, "PA") 311, a low-noise amplifier (hereinafter, "LNA") 313, a duplexer 315, and/or an antenna switch module (hereinafter, "ASM") 317. Each of the first to

fifth FEMs

310, 320, 330, 340, and 350 may include the PA 311 and the duplexer 315, and it may be referred to, for example, as a power amplifier module including a duplexer (PAMiD).

According to an embodiment, the first FEM 310 may include a switch 314. The switch 314 may select a signal intended to be detected among signals of a plurality of frequency bands. As an example, although FIG. 3 illustrates that the first FEM 310 includes the switch 314, other FEMs (e.g., the second to

fifth FEMs

320, 330, 340, and 350) may include the switch 314. The switch 314 included in the first FEM 310 may select any one of outputs of a coupler 312 of the first FEM 310, a coupler 322 of the second FEM 320, a coupler 332 of the third FEM 330, a coupler 342 of the fourth FEM 340, and/or a coupler 352 of the fifth FEM 350. For example, in FIG. 3, an output of the coupler 352 of the fifth FEM 350 may be connected to the switch 314 to be detected. The detected signal may be demodulated after being processed by a low pass filter (LPF) 382, an LNA 378, a mixer 376, a baseband low pass filter (BB LPF) 374, and/or an analog-to-digital converter 372.

According to an embodiment, if the frequency band that can be processed by the electronic device 101 is increased, the size of the switch 314 included in the first FEM 310 is increased, and thus the size of the first FEM 310 may also be increased. If the size of the first FEM 310 including the switch 314 is limited, the interval between respective ports of the switch 314 is narrowed, and interference may occur. For example, in case that the electronic device 101 supports the ENDC and simultaneously transmits signals of two frequency bands, the signals of the two frequency bands being simultaneously transmitted are all connected to one port of the switch 314 through the couplers, and only one of the signals may be detected through the switch 314. Because the signals of the two frequency bands being simultaneously transmitted are all connected to the one port of the switch 314 through the couplers, the two signals being simultaneously transmitted may be coupled to each other, and thus may exert an influence on the detected signal. If the signal being not desired to be detected is coupled to the signal being intended to be detected between the two signals being simultaneously transmitted, performance deterioration may occur. For example, if the frequency of the signal being not desired to be detected is equal to or similar to a multiplier of the frequency of the signal intended to be detected, the frequency component of the signal being not desired to be detected may be combined with a harmonic component of the frequency of a local oscillator (LO) of the mixer 376 to be down-converted into a baseband, and thus the demodulation performance may deteriorate.

As another example, intermodulation may occur between the signal being not desired to be detected and the signal intended to be detected in the low-noise amplifier 378 in the transceiver 370. Accordingly, a jammer may be formed in the frequency band of the signal intended to be detected, and the demodulation performance may deteriorate.

Hereinafter, an example in which the electronic device according to various embodiments of the disclosure resolves the deterioration of the demodulation performance with respect to the signal intended to be detected will be described.

FIG. 4 is a diagram illustrating an example configuration in which switches are connected in series according to various embodiments of the disclosure.

If the signal intended to be detected is selected through the switch 314 included in the first FEM 310 as shown in FIG. 3, interference may occur between the switch ports. According to various embodiments of the disclosure, the switch 314 included in the first FEM 310 may be connected in series to a switch 410 deployed outside the first FEM 310. In an embodiment, the switch 410, which can select any one of outputs of the coupler 332 of the third FEM 330, the coupler 342 of the fourth FEM 340, and the coupler 352 of the fifth FEM 350, may be deployed outside the first to fifth FEMs 310 to 350, and may be connected in series to the switch 314 of the first FEM 310. For example, the switch 314 of the first FEM 310 may select one of outputs of the coupler 312 of the first FEM 310, the coupler 322 of the second FEM 320, and the switch 410. As an example, as illustrated in FIG. 4, the signal being transmitted or received through the third FEM 330 may be detected through the

switches

314 and 410.

In an embodiment, the switch 410 deployed outside the first to fifth FEMs 310 to 350 may have superior inter-port isolation performance than the switch 314 included inside the first FEM 310. When being connected to the switch 314, the switch 410 and the second FEM 320 being not connected to the switch 410 may be respectively connected to the ports of the switch 314 spaced apart to secure the isolation.

FIG. 5 is a diagram illustrating an example configuration in which switches are connected to outside according to various embodiments of the disclosure.

In general, the isolation performance of the switch may be determined by the distance between ports. For example, the switch having a good isolation performance may have a relatively large size. In FIG. 5, in order to improve the isolation performance of the signal intended to be detected, a switch 510 securing the isolation between switch ports may be included.

In an embodiment, the switch 510 may select any one of outputs of the coupler 312 of the first FEM 310, the coupler 322 of the second FEM 320, the coupler 332 of the third FEM 330, the coupler 342 of the fourth FEM 340, and/or the coupler 352 of the fifth FEM 350. For example, as illustrated in FIG. 5, the signal being transmitted or received through the second FEM 320 may be detected through the switch 510.

In an embodiment, the inter-port isolation of the switch 314 may be lower than the inter-port isolation of the switch 510. As another example, the switch 314 may always be connected to the first FEM 310. As still another example, the switch 314 may be omitted, and the first FEM 310 may be directly connected to the switch 510.

FIG. 6 is a diagram illustrating an example configuration to detect signals of a plurality of frequency bands being simultaneously transmitted and/or received according to various embodiments of the disclosure.

In FIG. 6, explanation of the configurations similar to those of FIG. 3 may be not be repeated.

According to various embodiments, each FEM may further include at least one switch. As an example, the switch may control the direction of the signal detected through the coupler. The first FEM 610 may include a double pole double throw (DPDT) switch 614. According to an embodiment, the DPDT switch 614 may be connected to both ends of the coupler 612, the output port of the coupler 612, and a ground port. The DPDT switch 614 may control the direction of the signal being detected through the coupler 612. For example, if the DPDT switch 614 is connected in a forward direction, the detected signal may be output, whereas if it is connected in a reverse direction, the detected signal may not be output. The direction of the signal depending on the connection of the DPDT switch 614 will be described in greater detail below with reference to FIG. 7. The DPDT switch 614 can detect a transmission signal and a reception signal. The DPDT switch 614 can block the output of the signal, which is simultaneously transmitted and/or received, but is not desired to be detected, and thus the isolation performance of the signal intended to be detected can be improved.

In the disclosure, although the DPDT switch has been described by way of non-limiting example, any configuration capable of changing the direction of the signal flow may be possible.

According to an embodiment, the first FEM 610 may further include a switch 616. The switch 616 may connect or disconnect the output port of the coupler 612 to or from the switch 618. In case that the switch 616 is further included in the first FEM 610, the signal being detected through the output port of the coupler 612 can be blocked, and thus the isolation performance can be further improved.

According to an embodiment, in case that the switch 616 is included in the first FEM 610, a similar effect to the case where the switches are connected in series as shown in FIG. 4 can be obtained. As another example, in case that each of the respective FEMs includes the switch therein, it may be mounted on a printed circuit board (PCB), and may have a similar isolation effect to the case where the large switch is included as shown in FIG. 5.

According to an embodiment, in the same manner as the first FEM 610, the second FEM 620 may include a DPDT switch 624 and/or a switch 626, the third FEM 630 may include a DPDT switch 634 and/or a switch 636, the fourth FEM 640 may include a DPDT switch 644 and/or a switch 646, and/or the fifth FEM 650 may include a DPDT switch 654 and/or a switch 656. The switches included in the respective FEMs may have substantially the same functions as the switches included in the first FEM 610 as described above.

In FIG. 6, as an example, because the DPDT switch 634 of the third FEM 630 is connected in a forward direction, the switch 636 is connected to be "on", and the switch 618 of the first FEM 610 also selects the output of the coupler 632 of the third FEM 630, the signal of the frequency band being transmitted and/or received through the third FEM 630 can be detected.

FIG. 7 is a diagram illustrating an example state of a switch detecting signals of two frequency bands in case of simultaneously transmitting the signals of the two frequency bands according to various embodiments of the disclosure.

According to an embodiment, the electronic device (e.g., electronic device 101 of FIG. 1) may simultaneously transmit signals of two frequency bands, for example, a signal of the first frequency band and a signal of the second frequency band, among signals of a plurality of frequency bands. In FIG. 7, the signal of the first frequency band may be processed by the first FEM 710, and the signal of the second frequency band may be processed by the second FEM 720. FIG. 7 illustrates states of

switches

712, 714, 722, 724, 732, 734, and 736 included in

FEMs

710, 720, and 730 in case that the electronic device 101 detects the signal of the second frequency band as an example. The electronic device 101 may detect the signal of the second frequency band by configuring the DPDT switch 722 in the second FEM 720 in a forward direction and connecting the switch 724 to be "on". On the other hand, the electronic device 101 may block the signal of the first frequency band by configuring the DPDT switch 712 in the first FEM 710 in a reverse direction and configuring the switch 714 to be "off".

As another example, in case of detecting the signal of the first frequency band, the electronic device 101 may block the signal of the second frequency band by configuring the DPDT switch 722 in the second FEM 720 in a reverse direction and opening the switch 724. The electronic device 101 may detect the signal of the first frequency band by configuring the DPDT switch 712 in the first FEM 710 in a forward direction and connecting the switch 714 to be "on".

According to an embodiment, the third FEM 730 may further include a switch 736 selecting a signal for being detected between the signal of the first frequency band and the signal of the second frequency band.

According to an embodiment, in order to detect the signals for simultaneously transmitting the signals of the two frequency bands, at least one of the

switches

712, 722, 714, and 724 included in the first FEM 710 and the second FEM 720 may be adjusted in accordance with a divided time. According to an embodiment, at least one of the

switches

712, 722, 714, and 724 may be controlled by the communication processor 360.

According to an embodiment, even if the signals of the two frequency bands are simultaneously transmitted, the signals can be detected through the time division, and the isolation of the signal being detected using the switches in the FEMs can be increased. For example, different isolations can be secured in case that the electronic device 101 uses only the coupler and in case that the electronic device 101 connects the coupler and the DPDT switch and adjusts the direction of the DPDT switch. For example, in case that the electronic device 101 uses only the coupler, it is possible to secure the isolation of about 24 dB, and in case that the electronic device 101 connects the coupler and the DPDT switch and adjusts the direction of the DPDT switch, it is possible to secure the isolation of about 40 dB.

According to an embodiment, the electronic device 101 may increase the isolation by adjusting the direction of the DPDT switches 712 and 722 connected to the couplers in the FEMs. For example, additional isolation of about 16 dB can be increased through adjustment of the direction of the DPDT switches 712 and 722. The electronic device 101 may further include

switches

714 and 724 connected to the DPDT switches 712 and 722 and capable of blocking the output signals, and may additionally increase the isolation. For example, the electronic device 101 may include the DPDT switches 712 and 722 and the

switches

714 and 724, and may increase the isolation of about 30 to 40 dB. For example, the electronic device 101 may increase the isolation at the level of about 60 to 70 dB between the signal intended to be detected and the otherwise signal between the signals of the two frequency bands being simultaneously transmitted.

In an embodiment, the electronic device 101 may include a separate switch (e.g., switch 410 of FIG. 4) outside the

FEMs

710, 720, and 730. For example, at least one of the

switches

714 and 724 may be deployed outside the

FEMs

710 and 720. Accordingly, during demodulation of signals being detected and fed back, the performance deterioration due to intermodulation distortion (IMD) or harmonic with the signal, of which the detection is not desired, can be reduced.

FIG. 8 is a diagram illustrating an example configuration to detect signals of a plurality of frequency bands in case of simultaneously transmitting or receiving the signals of the plurality of frequency bands according to various embodiments of the disclosure.

According to an embodiment, the electronic device (e.g., electronic device 101 of FIG. 1) may include a communication processor (e.g., including processing circuitry) 360, a transceiver 370, a first FEM 810, a second FEM 820, and/or a third FEM 730. With reference to FIG. 8, the second FEM 810 or the configurations excluding the second FEM 820 may be substantially the same as those of FIG. 7.

According to an embodiment, the DPDT switch (e.g., DPDT switch 712 of FIG. 7) may not be included in at least one of the

FEMs

810, 820, and 730. According to an embodiment, in the first FEM 810, the transmission signal of the first frequency band may be detected or blocked by the switch 812, and the reception signal may be detected or blocked by the switch 814. As another example, in the second FEM 820, the transmission signal of the second frequency band may be detected or blocked by the switch 822, and the reception signal may be detected or blocked by the switch 824.

As an example, in FIG. 8, because the switch 822 of the second FEM 820 is connected to be "on", and the switch 736 of the third FEM 730 is connected to the switch 822 of the second FEM 820, the transmission signal of the second frequency band being processed by the second FEM 820 can be detected.

FIG. 9 is a flowchart illustrating an example method for detecting signals of a plurality of frequency bands in case that an electronic device simultaneously transmits or receives the signals of the plurality of frequency bands according to various embodiments of the disclosure.

According to various example embodiments of the disclosure, the electronic device (e.g., electronic device 101 of FIG. 1) may include a communication processor (e.g., CP 360 of FIG. 3), a transceiver (e.g., transceiver 370 of FIG. 3), and/or a plurality of front end modules (e.g., a first FEM 610 and a second FEM 620 of FIG. 6). The plurality of front end modules may further include a switch (e.g., a double pole double throw (DPDT) switch 614 of FIG. 6), and/or a coupler (e.g., coupler 612 of FIG. 6).

According to various embodiments of the disclosure, at operation 910, the electronic device 101 may simultaneously transmit and/or receive signals of a plurality of frequency bands. For example, the electronic device 101 may identify whether to simultaneously transmit or receive a plurality of signals. The electronic device 101 includes a plurality of FEMs (e.g., first to

fifth FEMs

610, 620, 630, 640, and 650 of FIG. 6), and thus can simultaneously transmit or receive the signals of the plurality of frequency bands.

According to various embodiments of the disclosure, at operation 920, the electronic device 101 may select a signal detected from the signals being simultaneously transmitted or received. The signal detection may be performed using couplers (e.g.,

couplers

612, 622, 632, 642, and 652 in the first to fifth FEMs of FIG. 6) included in the plurality of FEMs, and the signal for being detected may be one of the signals of the plurality of frequency bands, and may be selected through a switch (e.g., switch 618 of FIG. 6). The electronic device 101 may include at least one switch (e.g., switch 618 of the first FEM of FIG. 6), and may select the signal for being detected through the at least one switch. As an example, if the switch (e.g., switch 636 of the third FEM 630 of FIG. 6) is connected to be "on", or if the double pole double throw switch is connected in a forward direction (e.g., double pole double throw switch 634 of the third FEM 630 of FIG. 6), the signal passing through the switches (e.g., the double pole double throw switch 634 of the third FEM 630 of FIG. 6, the switch 636 of the third FEM 630, and the switch 618) may be detected.

According to various embodiments of the disclosure, at operation 930, the electronic device 101 may block the signal excluding the signal selected to be detected between the signals being simultaneously transmitted and/or received. For example, the blocking may be performed using the switch (e.g., switch 626 of the second FEM 620 of FIG. 6). In another embodiment, the electronic device 101 may perform the blocking by changing the transmission direction of the signal being blocked using the double pole double throw switch (e.g., double pole double throw switch 624 of the second FEM 620 of FIG. 6) to the reverse direction.

According to various embodiments of the disclosure, at operation 940, the electronic device 101 may demodulate the signal selected and detected. A feedback path, which is a path for processing the detected signal to be demodulated, may be the same path regardless of the frequency band of the signal being detected. The feedback path may be, for example, a path in which the detected signal is processed until the signal is demodulated through the transceiver after the switch (e.g., switch 618 in the first FEM 610 of FIG. 6) for selecting the signal for being detected. In another embodiment, in case of adding the double pole double throw switch (e.g., double pole double throw switch 634 of the third FEM 630 of FIG. 6), the electronic device may change the transmission direction of the double pole double throw switch to a forward direction in order to connect the signal being detected to the feedback path.

In another embodiment, the electronic device 101 may control the switches based on time using the processor. The electronic device may include a memory, and a program for controlling the switches may be stored in the memory.
